2、要:【目的】研究BGA土壤調(diào)理劑在不同土壤類型中對甘蔗苗期生長的影響,為BGA土壤調(diào)理劑在生產(chǎn)上的應用提供參考?!痉椒ā恳怨鹛?2—281和R0c22作為試驗品種,采用室外桶栽試驗,分別以壤土和粘土為栽培基質(zhì),設不同BGA施用量(0、2、4、6、8g瓜g土)處理及施用復合肥(1.2g/kg土)處理,測定不同處理對甘蔗苗期葉片葉綠素含量、株高和葉片營養(yǎng)元素含量。【結果】桶栽甘蔗施用BGA土壤調(diào)理劑,可促進甘蔗苗期的生長,提高葉片葉綠素含量,增加植株高度,明顯提高甘蔗葉片中N、K含量。在同類型土壤條件下不同甘蔗品種
3、間的效應一致,而對于同一甘蔗品種下粘土施用效果比壤土顯著,其中6、8班g土施用量的促進效果較顯著?!窘Y論】BGA土壤調(diào)理劑對桶栽甘蔗苗期生長具有促進作用。關鍵詞:土壤調(diào)理劑;BGA;甘蔗;苗期;生長效應中圖分類號:S156.2文獻標志碼:A文章編號:2095—1191(2013)03一0442一05InnuenceofapplyingBGAconditionerongrowthofsugarcaneseedlingLIANGQiang,XIANWu,GUIYi—yun,LEIJing—chao,F(xiàn)ANGFeng
